Well, that's good to hear. I find it pretty amazing how "non-universal",
the "universal step and direction" concept really can be. Like you
noted, one combination is less fussy than another. It really takes some
patience and more often than not, a lucky roll of the dice to make
things work.

When it does "come around" though, well, lets just say I know that warm
and fuzzy feeling one gets.

Glad you got it.
